Dear Alan, It is true that you cannot melt down goldfill to reuse,
however, you can sell it back to the refiner for credit. I sell mine
back and use the credit to buy tools that I see and dream about but
am too cheap to directly purchase. It adds up quick. Just didn’t want
anyone out there to throw theirs away!
Also, to solder goldfill to silver, use easy to low/medium solder
(gold or silver depending on which would be less obtrusive visually),
use firescale retardant, and voile! works a treat. Good day, Suzanne
